Vertical Farming
Geography: Asia Pacific · East Asia · China
Vertical farms stack growing trays in climate-controlled buildings, using LED lights and hydroponics instead of soil and sunlight. Chinese facilities in Shanghai, Guangzhou, and Chengdu grow leafy greens, herbs, and strawberries year-round, independent of weather and season.
Sananbio and GrowSpec are scaling production. The technology can operate at -55°C using heat pump and LED systems, making it viable even in China's far north. Indoor farming produces 40x more food per square meter than conventional agriculture and uses 95% less water.
The constraint is energy cost. LED lighting consumes significant electricity, making vertical farming cost-competitive only for high-value crops (herbs, greens, berries) near urban centers where transport savings offset energy costs. As solar electricity prices continue to fall — driven by China's own panel manufacturing — the economics improve.
